=/ after the 4th page of your art gallery I almost stopped looking, literally, It was too much coolness to handle and envy was there.. you know. By far I saw some of the sickest drawings ever there's just so much detail it's crazy! They'r awesome and they are true inspiration =] I admire your drawings. Wanna do art like that some day.
depends on how you look at it, there are some really good pics that took forever whatever medium you use, the only difference in my mind that is with computers if you make a mistake you can just hit a button and undo it, while with paint or pen if you make a mistake you either cover it up [badly sometimes] or re-start.
also there are some like myself who use both mediums, i draw my stuff by hand and colour in on the computer.
